Germline Transmission:  Earliest citation of germline transmission: J:93411
Parent Cell Line:  Not Specified (ES Cell)
Strain of Origin:  C57BL/6
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsExon 2 of the epsilon 1 isoform, encoding the first methionine, was replaced by a neomycin resistance gene in opposite transcriptional orientation to the gene via homologous recombination. Western and immunofluorescence analysis confirmed the absence of protein in adult brain and sciatic nerve. (J:93411)
